Description Marek Mahut 2017-02-23 15:32:24 UTC

Description of problem:

We have seen a problem twice today on preview, where the resolution
provided by skydns became unavailable, fixed by a master API restart.

We are not able to find a hint about a root cause.

Comment 5 Clayton Coleman 2017-02-25 21:26:08 UTC

This has nothing to do with SkyDNS, the master apiserver is down for an extended period and either isn't restarted, can't restart, is restarted (fails) and drops logs out of journald, or is blocking on something in the OS for very long periods.

Comment 7 Clayton Coleman 2017-02-28 16:47:08 UTC

Has this recurred?

Comment 9 Michal Fojtik 2017-03-27 12:14:04 UTC

Is this still a problem?

Comment 10 Thomas Wiest 2017-03-27 19:46:37 UTC

Closing since we haven't seen this since and aren't able to reproduce it.
